Heroic Games Launcher and added to the Game Mode. Native resolution with FSR2 set to Quality preset. Most of the game ran at 25-30 FPS. Frankly, the game is quite slow-paced. Only problematic spots were the first boss fight in the forest during rain and the final shootout near the end of the game where it dipped to 17-18 FPS.
Use Aegis, which is also available on F-Droid.
I quite like their hardware. Only wish that their custom ROM support was better. I bought a Google Pixel 9 recently just for GrapheneOS support.
